A German advertisement showing an Asian woman getting aroused after smelling dirty laundry worn by white men has fueled anger in Seoul, with many women calling it racist and demanding an apology.

The commercial, produced by German DIY-store chain Hornbach, shows white men working outside in a garden before removing their sweaty clothing and dumping it in a box.

The ad then cuts to a grey, industrial city that resembles Tokyo, where an Asian woman buys a bag of dirty clothes -- previously worn by the men -- opens it and moans with pleasure, as the commercial ends with a slogan saying: "That's how the spring smells".

An online petition asking for a public apology from the German firm and the removal of the ad had secured almost 1,000 signatures by Thursday afternoon.

Angry users on social media accused the company of promoting stereotypes against Asian women.

"How many more Asian female voices will you need to take us seriously and be aware of your thoughtless deeds and apologise?" a South Korean woman tweeted to Hornbach, which uploaded the ad on March 15.

The German firm has defended the commercial, tweeting that it was not "racist" and showed the "decreasing quality of life in cities".

The firm also said that the industrial town featuring the Asian woman was meant to be a "fictional city", not one based in Asia.

But its critics were unimpressed, with another South Korean woman tweeting: "No matter what you say, the ad was inappropriate".

"Asian women in Western society have gone through numerous sexual assaults based on racial slurs.
